Human spermatozoa contain multiple targets for protein S‐nitrosylation: An alternative mechanism of the modulation of sperm function by nitric oxide?

7 Aug 2007

Abstract excerpt

Nitric oxide (NO) enhances human sperm motility and capacitation associated with increased protein phosphorylation. NO activates soluble guanylyl cyclase, but can also modify protein function covalently via S-nitrosylation of cysteine. Remarkably, this mechanism remains unexplored in sperm although they depend on post-translational protein modification to achieve changes in function required for fertilisation....
